Best Sandisk High Speed Memory Cards

Designed for action cameras and mobile devices, the Extreme 64GB microSDXC UHS-I Memory Cards from the industry leader in high-speed memory, SanDisk feature a storage capacity of 32GB and support maximum read speeds of 100 MB/s and maximum write speeds of 60 MB/s. These cards have also been designed with the V30 Video Speed Class rating, which guarantees minimum write speeds of at least 30 MB/s. All of this allows for users to immerse themselves in extreme sports videography and photography at resolutions of Ultra HD 4K (3840 x 2160) and Full HD (1920 x 1080). While these cards have been designed for cameras that are UHS-I / V30 compatible, it may also be used in devices that do not support UHS-I / V30. However, bear in mind that these cards will then default to your device's speed class and bus rating, such as UHS-I and U3, which also supports minimum write speeds of 30 MB/s, UHS-I and U1, which supports minimum write speeds of 10 MB/s, or Class 10, which also supports minimum write speeds of 10 MB/s.
